Is child marriage an issue in Canada? Alissa Koski, a professor who researches the subject at McGill, says child marriage is "legal and ongoing" in every region in Canada, with provinces issuing more than 3,000 marriage licences to children over the last 18 years. While Canada condemns the practice abroad, Koski says there has been very little reflection on the practice's legality in our own country. Koski joins John now to discuss child marriage and some of the tricky ethical questions around child marriage.
